BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic enclosing and sealing machine provided with an envelope bender for facilitating insertion of the enclosed product into an envelope.

[0002]

2. Description of the Related Art As an automatic enclosing and sealing machine of this type, FIG.
As shown in FIG. 1, the first and second conveyors 1 and 2 are installed with a space therebetween, and an insert guide 4 which is rotated by a rotation shaft 3 is provided between the first and second conveyors 1 and 2. At the same time, an insert table 5 that moves from the second conveyor 2 to the first conveyor 1 is provided, and an envelope stacking device 7 that stacks envelopes 6 is provided above the insert guide 4.
Further, it is known that an enclosed material loading device 9 for loading the enclosed material 8 is provided on the upper part of the second conveyor 2.

In this automatic enclosing and sealing machine, one of the envelopes 6 is sucked by a suction device 10 provided in the lower part of the envelope stacking device 7, pulled down by a feed roller 11, and pulled out by a feed roller 12. Is fed downward, and while the glue allowance 6a of the envelope 6 is sandwiched by the feed rollers 12, the insert guide 4 rotates as shown in FIG. 7, and the tip end of the insert guide 4 as shown in FIG. 4a contacts the envelope 6.

When the tip 4a of the insert guide 4a comes into contact with the envelope 6, the bender 13 comes into contact with the opposing surface of the envelope 6 so that the glue allowance 6a of the envelope 6 is bent to the upper side, as shown in FIG. As described above, the tip 4 a of the insert guide 4 is inserted into the envelope 6.

Further, as shown in FIG. 7, while the envelope 6 is being supplied, the same enclosure 8 is supplied from the enclosure stacking device 9 onto the second conveyor 2, and then the second conveyor 2 is supplied. By rotating, it is sent on the insert table 5, the insert table 5 moves to the upper part of the 1st conveyor 1, and the same enclosure 8 is inserted in the envelope 6, as shown in FIG.

[0006]

By the way, in the conventional automatic enclosing and sealing machine, since the bender 13 is constituted by a fixed rod-shaped body, when the tip 4a of the insert guide 4 contacts the envelope 6, 4, the tip 4a of the insert guide 4 must be spaced apart from the bender 13, and therefore the insertion of the tip 4a of the insert guide 4 becomes shallow,
As shown in FIGS. 11 and 12, the bending position 14 of the envelope 6
There is a problem that the interval between a and 14b becomes narrow and the insert guide 8 is difficult to insert.

[0007]

According to the present invention, after inserting an insert guide into an envelope supplied from an envelope stacking device,
In an automatic enclosing and sealing machine that inserts the enclosed matter supplied from the enclosed matter loading device into the envelope by an insert table, when inserting the insert guide into the envelope,
An envelope bender is provided in the vicinity of a position where the tip of the insert guide hits the envelope, and a rubber bend roller that is pressed by a spring so as to contact the envelope is provided.

[0008]

In the present invention, when the insert guide rotates and comes into contact with the envelope so that the tip of the insert guide is deeply inserted into the envelope, the bender allows the spring to escape the contact of the tip of the insert guide.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1, 1 is a first conveyor, 2
Is a second conveyor, 3 is a rotary shaft, 4 is an insert guide, 4a is a tip, 5 is an insert table, 6 is an envelope,
Reference numeral 7 is an envelope stacking device, 8 is an enclosed product, 9 is an enclosed product loading device, 10 is a lid opening / closing device, 11 is a supply roller, and 12 is a feed roller. These configurations are the same as those of the conventional example. Although not described, in the present embodiment, the vendor 15
Is a rubber bend roller 15a and a bend roller 15a.
A spring 15b for pressing is provided.

In this embodiment, as shown in FIG. 2, when the tip 4a of the insert guide 4 is inserted into the envelope 6, the tip 4a of the insert guide 4 is brought into contact with the inner surface from the glue margin 6a of the envelope 6 It hits the bend roller 15a of the bender 15 via 6, but at that time, the spring 15 of the bender 15
Since the bend roller 15a escapes by b, the tip 4a of the insert guide 4 is bent widely at the margin 6a of the envelope 6 and its vicinity, and the tip 4a of the insert guide 4 is deeply inserted into the envelope 6 as shown in FIG.

In this way, the insert guide 4 has the envelope 6
4 and 5, the glue margin 6a of the envelope 6 and its vicinity are widened, and the space between the bending points 16a and 16b is widened, so that the enclosure 8 can be easily inserted. .

[0012]

As described above, in the automatic enclosing and sealing machine of the present invention, by providing the bend roller and the spring in the bender, the tip of the insert guide is deeply inserted into the envelope, and at that time, the bend roller of the bender is moved by the spring. Since it escapes from the tip of the insert guide, the insert guide can be rotated smoothly and the envelope can be opened greatly.
